Stablecoins Explained
A stablecoin is a crypto token designed to hold a steady value, almost always one US dollar. They exist because moving in and out of ordinary bank money is slow, while moving between crypto tokens is instant. Browse the largest ones on our stablecoins page.
The three main designs
- Fiat-backed. A company holds dollars and short-term government debt in reserve and issues one token per dollar. This covers the large majority of the market. The key question is whether the reserves are real, liquid and audited.
- Crypto-backed. Users lock volatile crypto worth more than the tokens they mint, so the system stays solvent even if prices fall. Transparent, but capital inefficient.
- Algorithmic. Supply is expanded and contracted by code with little or no real collateral. This design has failed repeatedly and spectacularly, most notably in 2022.
What people use them for
Traders park funds in stablecoins between positions without leaving crypto. People in countries with high inflation use them as informal dollar savings. Businesses use them for cross-border payments that settle in minutes rather than days. They are also the base currency of most DeFi lending markets.
The risks behind the word stable
- Reserve risk. If the issuer's assets are not what they claim, the peg is a promise rather than a fact.
- Freeze risk. Centralised issuers can and do freeze addresses when ordered by authorities.
- Depeg risk. Even well-backed stablecoins have briefly traded below a dollar during banking stress.
- Yield risk. Earning interest on stablecoins means lending them to someone. The dollar may be stable, the counterparty may not be.

Frequently Asked Questions
Are stablecoins actually backed by dollars?
The large fiat-backed issuers publish attestations showing reserves in cash and short-term treasuries. Quality varies, so it is worth reading who audits them and how often, rather than assuming.
Can a stablecoin lose its peg?
Yes. Algorithmic designs have collapsed entirely, and even reserve-backed tokens have traded below a dollar temporarily during market or banking stress before recovering.
Is holding stablecoins the same as holding dollars?
Economically it is similar, legally it is not. You are holding a claim on a private issuer, without deposit insurance, plus the technical risk of the blockchain and smart contracts involved.
